资料介绍

 

Supercapacitors (or ultracapacitors) are fi nding their wayinto an increasing number of applications for short-termenergy storage and applications that require intermittenthigh energy pulses. One such application is a power ridethroughcircuit, in which a backup energy source cutsin and powers the load if the main power supply failsfor a short time. This type of application has typicallybeen dominated by batteries, but electric double layercapacitors (EDLCs) are fast making inroads as theirprice-per-farad, size and effective series resistance percapacitance (ESR/C) continue to decrease.
